Description

The present invention relates to a device for slicing a food product, in particular high-performance slicer. The food products may be, for example, sausage, ham, meat, cheese, bread or the like.

Such slicing devices are basically known. An exemplary slicing device is in the DE 101 48 595 A1 described. Hereinafter, a slicing device is also referred to as a slicing machine.

A slicing device comprises a cutting knife, which is typically arranged on a slicing device of a knife assembly and rotates in a cutting plane rotationally and / or planetary. For driving the cutting blade, the blade assembly further comprises a drive. By means of a product feed, food products can be fed to the cutting plane in one lane or in several parallel lanes. By the rotating cutting blade discs are separated at the front end of the supplied products, which fall on a lying below the cutting plane product tray. From there, the slices, preferably in the form of portions consisting of several slices, are transported further in order, for example, to feed them. to supply a packaging unit.

It may be necessary or desirable to be able to accurately adjust the position of the cutting blade in the cutting plane, for example with respect to an associated cutting edge forming the front end of the product feed viewed in the conveying direction of the food products. As a result, the slicing operation can be improved.

In addition, it may be necessary or desirable to be able to adjust the cutting plane at least slightly, for example to align it parallel to the cutting edge and / or to a so-called cutting gap extending between the cutting plane and the cutting edge and eg from the EP 2 829 372 A1 is known to be able to adjust better.

The present invention has for its object to provide a simple to produce slicing device, wherein the cutting blade is adjustable.

The object is achieved by a device having the features of claim 1. Preferred embodiments and further developments of the invention are described in the dependent claims.

A device according to the invention for slicing a food product comprises a knife assembly, comprising a slicing device with a cutting blade arranged thereon or arrangeable, circulating in a cutting plane and a drive for the cutting knife and a holder for the knife assembly, in particular formed by a machine frame of the device Knife assembly and the holder for adjusting the cutting blade in the cutting plane at least by means of a first linear guide and at least substantially parallel to the first linear guide second linear guide are coupled together such that the blade assembly along a plane parallel to the cutting plane extending first direction, in particular vertical or Y direction , is adjustable relative to the holder, and wherein for storage of the blade assembly relative to the holder, the first linear guide at least one fixed bearing and the second linear guide wen at least one floating bearing has.

In the apparatus according to the invention the adjustability of the cutting blade is achieved in that the knife assembly, on the slicing the cutting blade can be mounted or mounted, is mounted by means of the two linear guides along the first direction adjustable on the holder. The cutting blade can thus be adjusted along the first direction and e.g. adjusted with respect to a cutting edge and / or a shell mold.

In slicing machines known from the prior art, a support surface, which is inclined relative to the horizontal, is frequently used for the products to be supplied, which means that the cutting plane extending at least substantially perpendicularly to the contact surface is inclined to the vertical. A slicing machine with inclined product feed and cutting plane is for example on the EP 2 543 484 A1 known. With the first direction is therefore preferably meant the direction along which the cutting blade can be adjusted in height, regardless of whether this direction is inclined in the vertical direction or to the vertical.

The holder may be a machine frame or a machine frame of the slicing device. The holder can be designed to be rigid and stable, whereby the blade assembly can also be stored in a stable manner, which is particularly important for the slicing operation.

For storage of the blade assembly relative to the holder, the first linear guide on a fixed bearing. This will provide a secure coupling between the blade assembly and the bracket achieved, so that the blade assembly can be kept in a stable manner, in particular during the cutting operation. The fixed bearing allows an adjustment of the blade assembly along the first direction. The second linear guide has a floating bearing, which also allows the adjustment along the first direction. However, the movable bearing can also allow a movement of the blade assembly relative to the holder in a direction parallel to the cutting plane and perpendicular to the first direction extending second direction, preferably horizontal or X-direction.

By the fixed bearing on the side of the first linear guide and the movable bearing on the side of the second linear guide lower accuracy requirements can be made, whereby the production of a slicing simplified and cost can be reduced. If, for example, only fixed bearings are permitted in both linear guides, which only permit movement along the first direction, high demands must be made e.g. be set to the parallelism and dimensioning of the two linear guides, which are not required by the floating bearing on the side of the second linear guide, since the floating bearing also allows movement of the blade assembly relative to the support in the second direction, whereby e.g. a non-exact parallel course of the two linear guides can be compensated. The expense to be incurred for the manufacture, assembly and adjustment of the holder, the knife assembly or the two linear guides can therefore be reduced. For example. For example, milled parts that are relatively accurate can be made by lower cost processes that result in less accurate parts.

According to a preferred embodiment of the invention, the first linear guide is designed as a fixed bearing and the second linear guide is designed as a floating bearing. For storage of the blade assembly relative to the holder by means of the first linear guide exclusively at least one fixed bearing can be used, while for storage of the blade assembly relative to the holder by means of the second linear guide exclusively at least one floating bearing is used.

The holder can in particular be designed as a kind of frame which surrounds or surrounds the blade assembly. The receptacle protrudes from the outside from the holder to the knife assembly. The sliding profile provided on the side of the blade assembly may be received in the receptacle such that it is movably mounted in the receptacle along the first direction. Further, the receptacle may allow movement of the sliding profile along the second direction.

According to a preferred embodiment of the invention, the receptacle has at least one movable part and an adjusting device for the movable part, wherein by adjusting the movable part, the position of the receptacle, in particular in the third direction, is adjustable and / or wherein by adjusting the movable part the clamping of the sliding profile in the receptacle is adjustable. By adjusting the position of the receptacle in the third direction, the cutting plane can be adjusted and in particular aligned with respect to a cutting edge. By adjusting the clamping of the sliding profile in the receptacle, the mobility of the sliding profile can be changed relative to the receptacle along the second direction.

Preferably, the receptacle has two associated, in particular cylindrical, pins which are arranged laterally next to the blade assembly on the holder and which form between them a gap open to the blade assembly for receiving the sliding profile, wherein the width of the gap, with respect to the third Direction, at least approximately the width of the sliding profile corresponds. Through the two pins and the intermediate, open gap, a receptacle for the sliding profile can be realized in a structurally simple manner, which allows a mobility of the sliding profile along the first direction and the second direction.

Preferably, each pin is hollow cylinder-shaped and mounted on a cylindrical, fixed to the bracket bolts, wherein between pins and pins a hollow cylinder is arranged, which is rotatable relative to the pin and the pin in the circumferential direction, in particular by means of a tool, and wherein the hollow cylinder a along the circumferential direction has varying thickness for eccentric mounting of the pin and bolt. It is preferably provided that the thickness of the hollow cylinder along the circumferential direction varies such that by rotation of the hollow cylinder, the gap width and / or the position of the gap for receiving the sliding profile, in particular with respect to the third direction, are adjustable / is. By means of appropriate adjustment of the cooperating with the two pins hollow cylinder thus the position of the receptacle formed by the pin, in particular in the third direction, can be adjusted, and / or the clamping of the sliding profile between the two pins can be adjusted.

Preferably, between each peg and the slide profile is a sliding material preferably arranged on the respective peg, e.g. made of plastic, provided. Thereby, the lubricity of the sliding profile can be improved relative to the pin.

For adjusting the knife assembly relative to the holder along the first direction, a spindle drive may be provided, which comprises at least one spindle and a drive, in particular chain drive, for the spindle, the drive preferably offset in the first direction to the blade assembly, in particular above the blade assembly , is arranged on the holder.

Due to the spindle drive, a precise adjustment along the first direction can be achieved. In addition, the knife assembly set in the first direction can be held securely and firmly in the set position by means of the spindle drive, which is particularly important for the slicing operation.

Preferably, the spindle extends along the first direction between the holder and the knife assembly, and a spindle nut fixed to the knife assembly is associated with the threaded spindle, preferably threaded onto the threaded spindle. About the spindle nut, a rotational movement of the spindle can be converted into a translational movement of the blade assembly along the first direction.

Preferably, the position of the fixed bearing relative to the holder along the first direction and / or the orientation of the fixed bearing are relative to a plane perpendicular to the first direction adjustable plane. By adjusting the position and / or the orientation of the fixed bearing, the orientation of the spindle can be adjusted.

According to a preferred embodiment of the invention, the blade assembly comprises a frame via which the blade assembly is adjustably coupled to the holder along the first direction, and a carrier device for the slicing device and the drive, which in turn is coupled to the frame. In this case, the frame and the carrier device are coupled to each other by means of a third linear guide and a third linear guide at least substantially parallel, fourth linear guide for adjusting the support means along the second direction relative to the frame. The position of the cutting blade can thus also be adjusted along the second direction.

For mounting the carrier device relative to the frame, the third linear guide preferably has at least one fixed bearing, and the fourth linear guide preferably has at least one movable bearing. The requirements to be placed on manufacturing tolerances can be lowered by the use of the movable bearing, in particular in comparison to a use of fixed bearings both on the side of the third linear guide and on the side of the fourth linear guide.

The carrier device may form in its lower edge region and / or on its underside a partial region which rests on an associated sliding surface of the frame of the blade assembly for forming a movable bearing.

The device according to the invention is characterized by a number of advantages.

A modular overall structure is made possible by the fact that modules with mounting interfaces can be created by the invention. Both assembly and disassembly are relatively easy. Furthermore, there are correction options during assembly and after setting up the device at the site.

The production requires less milling operations in the prefabrication of components, in particular of the machine frame, the cutter head, the blade assembly or their holder, since the number of reference surfaces for the component allocation is smaller than in the prior art. Instead of milled parts, prefabricated, less expensive welded parts can be used, to a greater extent than in the prior art.

In particular, the cutterhead housing, the cutting unit, its attachments and the machine frame can be modular and so used for different sizes.

Generally advantageous is the open design enabled by the invention, good visibility and good cleanability. In particular, cavities can be avoided or the number of cavities can be minimized. Furthermore, it proves to be advantageous that bearings and guides are basically more hygienic, easier to seal and longer lasting.

Furthermore, the invention enables a relatively rapid change of components such as e.g. Bearing shells.

In the 1 illustrated device 11 for slicing a food product 13 has a product edition 15 on, by means of which the product 13 conveyed in a conveying direction F and a rotating in a cutting plane E cutting blade 17 can be supplied. The cutting knife 17 separates from the front end of the product 13 slices 19 starting on a product tray 21 fall and be stacked there for example to a serving. One on the product shelf 21 Portion formed is further conveyed along the conveying direction F and fed, for example, to a downstream packaging device (not shown). The front end of the product support seen in the conveying direction F. 15 has a cutting edge 23 on which a counter blade to the cutting blade 17 forms. The cutting edge 23 For example, from one at the front end of the product support 15 mounted closure element are formed, which may also be formed as a shell mold.

During the slicing operation, the cutting blade moves 17 in the cutting plane E. The cutting knife 17 is then located at a distance in front of the cutting edge 23 which corresponds to a desired, adjustable cutting gap. The distance refers to the conveying direction F.

In the device of 1 is the product edition 15 inclined to the horizontal. Accordingly, the cutting plane E does not extend in the vertical direction, but is inclined with respect to the vertical direction. The inclination angle can be about 40 ° relative to the vertical.

The location of the cutting blade 17 in relation to the supplied product 13 and / or with respect to the cutting edge 23 is adjustable, in the cutting plane E along a first direction defined by the Y-axis. The first direction is in the device according to 1 inclined to the vertical and runs in the cutting plane E downwards or upwards.

The cutting knife 17 can also along a defined by the X-axis second direction (see. 3 and 4 ), which extends perpendicular to the first direction in the cutting plane E, are adjusted.

Further, the cutting plane E may be aligned in a third direction defined by the Z-axis, the third direction being perpendicular to the first and second directions. This may be necessary or desirable to keep the cutting plane E parallel to the cutting edge 23 align.

Unlike the device of 1 runs in the device of 2 the product edition 15 in the horizontal direction and the cutting plane E extends in the vertical direction. The first direction and thus also the Y-axis therefore extend in the vertical direction. The second direction and the X-axis extend in the cutting plane E in the horizontal direction and the third direction or the Z-axis is perpendicular to the cutting plane E also in the horizontal direction.

In the device 11 of the 2 is one the cutting knife 17 having knife assembly 25 shown schematically. The knife assembly 25 includes a slicing device 27 with a receptacle for the cutting blade 17 on which the cutting blade 17 attached, as well as a drive 29 for driving the cutting blade 17 , Such a knife assembly 25 is also in the device of 1 intended.

As already stated above, it is necessary or desirable, the position of the cutting blade 17 to be able to adjust in the cutting plane E. In addition, it may be desirable to be able to align the cutting plane E, for example with respect to the cutting edge 23 ,

To accomplish the mentioned adjustability, the knife assembly is 25 on a bracket 31 arranged (cf. 3 and 4 ), which is the machine frame of the slicing device (cf. 1 and 2 ) can act. Here are the knife assembly 25 and the holder 31 for adjusting the cutting blade 17 in the cutting plane E at least by means of a first linear guide 33 and one to the first linear guide 33 parallel second linear guide 35 coupled together so that the blade assembly 25 along the direction parallel to the cutting plane E extending first direction, with respect to the to 1 and 2 made statements along the Y-axis, relative to the bracket 31 is adjustable.

For storage of the knife assembly 25 opposite the bracket 31 has the first linear guide 33 two along the first direction, ie along the Y-axis, spaced from each other fixed bearing FL. In contrast, the second linear guide 35 two along the first direction spaced apart bearing L for storage of the blade assembly 25 opposite the bracket 31 on.

The knife assembly 25 in particular has a frame 37 on, about the knife assembly 25 with the bracket 31 is adjustably coupled along the first direction. In addition, the knife assembly points 25 one with the frame 37 coupled carrier device 39 for the slicing device 27 with the cutting knife 17 and the drive 29 on. The frame 37 and the carrier device 39 are by means of a third linear guide 41 and one to the third linear guide 41 parallel fourth linear guide 43 for adjusting the carrier device 39 along the second direction, ie along the X-axis, relative to the frame 37 coupled together. For storage of the support device 39 opposite the frame 37 are on the side of the third linear guide 41 in turn provided two fixed bearing FL, which are offset with respect to the second direction to each other. Furthermore, the fourth linear guide 43 two along the second direction offset from each other arranged floating bearing L on.

The floating bearings L are of two downwardly directed projections 77 at the bottom of the carrier device 39 formed on an associated sliding surface 79 of the frame 37 rest, permitting mobility both along the first direction and along the second direction.

The fixed bearings FL are made of a rod-like or tubular upper element 81 the frame formed, the two guide shots 83 embrace the exact fit on the support device 39 arranged and along the second direction along the element 81 are movable while no movement along the first direction is allowed. The guide shots 83 can like the guide shots described in more detail below 47 be educated.

The carrier device 39 on which the cutting knife 17 is attached, is opposite the frame 37 along the second direction, ie along the X-axis, adjustable, while the frame 37 opposite the bracket 31 along the first direction, ie along the Y-axis, is adjustable. This allows the cutting blade 17 be adjusted both along the X-axis and along the Y-axis.

The first linear guide 33 points along the first direction, ie along the Y direction Axle, extending guide tube 45 on, at its two axial ends fixed to the bracket 31 connected is. Furthermore, the first linear guide 33 two guide receptacles spaced apart along the first direction 47 on. Every leadership shot 47 is stuck with the frame 37 connected.

As the 5 shows, embraces the guide 47 the guide tube 45 , The guide shot 47 is designed in the manner of a sliding block, the two bearing shells 49 that is on the frame 37 are screwed on and the guide tube 45 embrace. It is between each bearing shell 49 and the guide tube 45 a plastic element 51 attached to the respective bearing shell 49 is attached. Through the plastic element 51 is the lubricity of the bearing shell 49 along the guide tube 45 improved. Because the cups 49 on the bracket 31 screwed on, a simple assembly or disassembly is possible.

The combination of guide rod 45 and leadership shot 47 forms a respective bearing FL of the first linear guide 33 , The respective fixed bearing FL allows adjustment along the first direction, ie along the Y-axis, while it does not allow adjustment along the second direction, ie along the X-axis.

The frame 37 has a rod-shaped slide profile extending along the first direction 53 on, in two offset images 55 engages the one at the side of the slide 53 lying carrier 57 the holder 31 are provided and one to the sliding profile 53 open gap 59 exhibit. The pictures 55 form in combination with the sliding profile 53 the second linear guide 35 , In this case, the sliding profile 53 with respect to the first direction along the photographs 55 be adjusted. The pictures 55 also allow one, at least slight, movement of the slide 53 in the second direction too. This is from the following with reference to the 6 and 7 made statements in more detail.

Every shot 55 has two associated, cylindrical pin 61 on, which are offset with respect to the third direction, ie with respect to the Z-axis, to each other and between them the gap 59 form. The gap width corresponds to at least approximately the width of the sliding profile 53 , At every pin 61 is a, for example made of plastic, sliding material 63 arranged to the sliding ability of the sliding profile 53 regarding the recording 55 to improve.

Every pin 61 is hollow cylindrical and formed on a bolt 65 attached, the axial end of the carrier 57 is attached. Between the bolt 65 and the pin 61 is a hollow cylinder 67 arranged, opposite the bolt 65 and the pin 61 in the circumferential direction U of the pin 61 is rotatable. For this purpose, the hollow cylinder 67 at his from the porter 57 opposite axial end two recesses 69 on, in the front by means of a tool can be intervened, to the hollow cylinder 67 in the circumferential direction U to twist.

The hollow cylinder 67 has along the circumferential direction U a varying thickness, measured in the radial direction, on, so that the pin 61 opposite the bolt 65 is mounted eccentrically. The hollow cylinder 67 thus forms a kind of eccentric around the central bolt 65 , By turning a respective hollow cylinder 67 can thus the associated pin 61 and thus also the contact surface for the sliding profile 53 be adjusted in particular with respect to the Z-direction. Thus, for each shot 55 the gap width and / or the position of the gap 59 for receiving the sliding profile 53 , in particular with respect to the third direction, at least slightly adjusted. By changing the gap width, the clamping of the sliding profile 53 in the respective recording 59 to be changed. In addition, by adjusting the position of the gap 59 with respect to the third direction, the orientation of the cutting plane E are changed, as this by adjusting the position of the gap 59 at least slightly to that of the guide tube 45 defined axis can be pivoted. As a result, at least a slight alignment of the cutting plane E or the cutting blade 17 for example, with respect to the cutting edge 23 will be realized.

That of the carrier 57 opposite axial end 71 of the bolt 65 has an external thread on which a nut 73 is screwed by means of the respective pin 61 at the bolt 65 is secured. Hygienic seals can be under the mother 73 and between the carrier 57 and the carrier 57 facing end face 75 of the pin 61 be provided.

The holder 31 has a housing at the top 85 for a spindle drive 87 on, the two essentially parallel spindles 89 includes, which are guided through the housing bottom and extending in the Y direction downwards. On every spindle 89 is a spindle nut 91 Threaded on the frame 37 is fixed. About the spindle nuts 91 becomes a rotary motion of the spindles 89 in a translational movement of the frame 37 along the first direction, ie along the Y-axis implemented.

Every spindle 89 has at its axial upper end a gear 93 on, in a via a drive (not shown) driven chain 95 intervenes (see. 8th and 9 ). The realized chain drive for the spindles 89 is advantageous because it has an alignment of the spindles 89 allows, as described below.

Every spindle 89 is in the case 85 by means of a fixed bearing FL and a movable bearing L stored. The fixed bearing FL has a block 97 on, in which the respective spindle 89 Eg is stored by means of a rolling bearing, in such a way that the spindle 89 can not move in the axial direction. The block 97 is about three screws 101 on the housing 85 supported, the distance adjustment to the housing 85 serve. These are adjusted according to the cabinet hinge principle. Then the three cylinder screws 99 tightened to the block 97 to fix in its adjusted position. The orientation of each spindle 89 can thus be adjusted. In particular, so can the position of the respective spindle 89 relative to the housing 85 along the first direction and the orientation or orientation of the spindle 89 be adjusted relative to a direction perpendicular to the first direction extending plane.

The arranged on the bottom wall vertical plate 103 serves as a guide for the block 97 , being a projection 105 of the block 97 in a recess of the plate 103 intervenes. Two horizontally arranged stud bolts 107 serve as a horizontal adjustment aid, because their front side acts on an associated surface of the block 97 ,

The movable bearing L is located on the lower wall of the housing 85 and allows the adjustment of the spindle described above 89 , The movable bearing L preferably has a U-shaped running plate 109 on, for clamping a spindle 89 surrounding clamping bush 111 serves. The plate 109 is on the clamping bush 111 pushed and secured by means of a fixed to the housing wall pin. With the preferably four cylinder screws 113 becomes the plate 109 together with the socket 111 adjusted in height and then clamped with the respective lock nuts. So that the clamping bush 111 be pulled from the bottom and thus from the outside close to the outer housing wall. Also you can achieve a good tolerance compensation, as with the screws 113 is adjusted not only in the axial direction, but also on the installation angle between the spindle 89 and the housing wall can be influenced.

For adjustment along the second direction, as along the X direction, another spindle drive is provided with a between the frame 37 and the carrier device 39 arranged spindle 115 ,
